Description

  The present invention relates to an electric tulip installed in a pachinko gaming machine.

  As is well known, the electric tulip has a pair of wing pieces that open and close on the left and right sides of the prize opening that opens on the front surface of the mounting board, and always holds the left and right wing pieces in an upright closed position. While making it difficult or impossible for the ball hitting the board to fall, when the release instruction signal is received, the solenoid as a driving source is excited and the wing piece is tilted in the left-right direction by using the pull-in of the plunger. In this structure, the ball is allowed to jump into the open posture, and the ball is easily opened by utilizing the wide opening toward the left and right, so that a large number of winning balls can be received in a short time.

Furthermore, in order to convert the expansion / contraction movement of the solenoid plunger into the left / right rotation of the wing piece, this electric tulip has a rocking interlocking member interposed between them, and is accompanied by the expansion / contraction movement of the plunger. The swing interlocking member is swung in the vertical direction with the fixed support shaft as a fulcrum, and the swinging pin protruding from the back of the blade piece is moved in the vertical direction by this swinging so that the tip ends of both blade pieces are moved to the support shaft. Is pivoted in the left-right direction around the fulcrum to open and close.
At this time, the left and right wing pieces are driven by one solenoid, and the two wing pieces are simultaneously opened and closed by the expansion and contraction of the solenoid.

  The electric tulip thus constructed is located between the wing piece in the middle of rotation and the obstacle nail planted in the vicinity thereof when the wing piece opens and closes, for example, when changing from the closed posture to the open posture. The hit ball may be bitten, the wing piece stops rotating, and the conversion to the open posture stops. Since the stop of the rotation of the one wing piece is simultaneously linked to the other wing piece via the solenoid and the swing interlocking member, the rotation of the other wing piece that is free to rotate is stopped. As a result, both wing pieces cannot be converted to the open posture.

  This relationship is the same at the time of closing, and when rotating in the closing direction, for example, a plurality of hitting balls ride on the wing piece, or the wing piece is caught between obstacle nails and one wing piece is When the rotation is stopped, the other wing piece also stops rotating, and the open state continues despite the command to close it. There is a problem that disappears.

  In order to operate the right and left wing pieces at the same time, the problem of opening and closing movement due to the ball engagement of the wing pieces is to transmit one solenoid and the expansion and contraction movement of the solenoid to the wing pieces using one swing interlocking member. Since it occurs as a result of configuration and is often detrimental to the player, the actual situation is that an improvement is desired but no sufficient solution has been presented.

Conventionally, as a method for solving the situation in which the other wing piece cannot be opened and closed due to the inability to open and close generated in one wing piece, for example, an elastic body is provided at the tip of a member that transmits the expansion and contraction movement of the solenoid to the wing piece. When the rotation of one wing piece is stopped, the elastic member engaged with the protrusion of this wing piece is bent to allow the member to swing, thereby allowing the other wing piece to rotate. What is solved by doing is proposed by patent document 1. FIG.
One blade piece is interposed between a solenoid and a left and right blade piece by a rotating member corresponding to the swing interlocking member and a driving force transmission mechanism in which the interlocking member is assembled to the rotating member. For example, Japanese Patent Application Laid-Open No. H10-228707 proposes a method in which the interlocking member is rotated to ensure the rotation of the other blade piece when the rotation is restricted.
JP2003-284833A. JP 2002-263280 A.

  These inventions according to the existing proposals are those in which elastic bodies 3a1 and 3b1 are provided on parallel plate bodies 3a and 3b (Patent Document 1), and an interlocking member 80 is provided at the tip of a rotating member 74 (Patent Document 2). Although there is a difference, in each case, another component is assembled to the component that becomes the swing interlocking member, and the rotation of one blade piece is performed by the action of this additional component, that is, the elastic bodies 3a1 and 3b1 and the interlocking member 80. Although the impossible state is not affected on the other wing piece, these parts are extremely fine parts due to the nature of the apparatus, and accuracy is also required, so that their manufacture and assembly are extremely troublesome. Further, since it is frequently used, durability is required, and there is a problem that the unit price of the product is increased in order to obtain reliability.

In view of the above-described circumstances, the present invention improves when the rotation of one of the left and right wing pieces is stopped by ball engagement or the like so that the rotation of the other wing piece is not hindered by this stop. It was developed for the purpose.
In particular, the present invention avoids direct transmission of a failure occurring in one wing piece to the other wing piece without incorporating special parts between the solenoid and the left and right wing pieces, and is free to rotate. It is intended to provide an electric tulip in which the wing pieces can be rotated independently so as to prevent the left and right wing pieces from being simultaneously unrotatable due to a problem occurring in one wing piece. is there.

  In order to achieve the above object, the present invention provides a solenoid plunger serving as a drive source, and a swing interlocking member that converts the expansion and contraction movement of the plunger, that is, a linear reciprocating motion into a rotational motion of a blade piece, and transmits it. In the normal state, the left and right wing pieces are opened and closed at the same time. When one of the wing pieces becomes unrotatable due to ball engagement, etc., the wing piece remains stopped. The other blade piece is allowed to rotate and is opened and closed independently.

  More specifically, the present invention relates to a mounting board and a left and right side that converts a closed posture standing up and a released posture tilted in the left-right direction with pivots erected on the left and right of a winning opening opened on the mounting board. A wing piece, a solenoid that is on the back side of the mounting substrate and moves the plunger in accordance with an instruction to open and close the wing piece, and a left and right swinging individually interposed between the plunger of the solenoid and the left and right wing pieces And the left and right swing interlocking members are respectively supported by fixed supporting shafts, and both swing ends are supported freely, and one swing end is provided. The shaft is provided with a shaft connecting portion and a connecting shaft that is supported by the tip of the plunger is loosely fitted and connected with a required gap, while the other swinging end is provided with a push-up piece and a pressing piece facing each other. Forming a coupling receiving portion, The interlocking pins projecting from the back part of the wing piece are respectively slid on the receiving part, and the left and right oscillating interlocking members are arranged in an independent state between the solenoid and the left and right wing pieces. The two sway interlocking members are synchronously interlocked with the expansion and contraction of the plunger, and when one of the blade pieces becomes unrotatable, the shaft coupling portion of the swing interlocking member and the plunger An electric tulip characterized in that the connecting shaft is tilted by utilizing a gap between the connecting shafts, and one of the swing interlocking members that can freely swing is swung so that the other wing piece can be rotated. Is to provide.

According to the present invention, in the above-described electric tulip, the connecting shaft supported by the plunger is loosely penetrated through a through hole formed in the plunger so as to be loosely supported, and the swing of one swing interlocking member is supported. When the shaft stops, the one shaft end connected to the swing interlocking member is left at the stop position, and the through hole is tilted to the fulcrum so that the other swing interlocking member connected to the other shaft end can swing. It is to provide an electric tulip characterized by.

  Further, according to the present invention, the left and right wing pieces have a center of gravity located above the bearing position of the support shaft, and the center of gravity position is moved to the left and right around the support shaft during a turning operation. At the time of closing and opening, it is made to collide with a stopper that regulates the rotation range to maintain the closing posture and the opening posture, and the left and right swing interlocking members collide with each other at the time of closing and opening to control the swing range And a swinging range of the blade interlocking member and a swinging range of the swing interlocking member are individually regulated, and the swinging range of the swing interlocking member is set narrower than the swinging range of the blade fragment. On the other hand, when a required gap is provided between the interlocking pin of the blade piece and the pin connection receiving portion of the swing interlocking member, and when the blade piece abuts the stopper that regulates the rotation range, the gap causes the Direct connection between the pin connection receiving portion and the connection pin It is to provide an electric tulips were characterized by being obtained by avoiding catalyst.

Still further, the present invention is the above-described electric tulip, wherein the solenoid plunger is formed with a diameter smaller than the diameter of the insertion hole formed in the core of the solenoid so that a required gap is secured between the plunger and the insertion hole. When the swing motion of one swing interlocking member is stopped by the rotation stop of one blade piece, the plunger is rotated by the gap to absorb the strain generated between the other swing interlocking member. It is in providing the electric tulip characterized by doing.

By the way, in the electric tulip according to the present invention, the solenoid as a driving source is always kept in a demagnetized state, and the plunger is extended to a state where the plunger is pulled out by a spring contracted between the solenoid.
At this time, the left and right wing pieces are held in the closed posture via the swing interlocking member, and when the next opening instruction is given, the solenoid is excited to retract the plunger against the spring. The left and right wing pieces, which are contracted and closed through the swing of the swing interlocking member, are respectively rotated outward and released.

  The plunger and the oscillating interlocking member are connected via a connecting shaft, and a front end portion of the plunger is provided with a through hole for mounting the connecting shaft, and the connecting shaft is inserted laterally therethrough. It is designed to be pivoted. Then, both shaft ends are inserted and connected to shaft connecting portions formed at one of the swinging ends of the swing interlocking member.

  The swing interlocking member is supported so that both ends can freely swing by being supported by a fixed support shaft horizontally extending in the center of the length, and the shaft coupling provided at the one swing end. The part is formed as a through-hole penetrating sideways, and is connected by loosely fitting a connecting shaft thereto. The shaft connecting portion is loosely fitted by forming the through-hole diameter larger than the shaft diameter of the connecting shaft, whereby the connecting shaft inserted through the shaft connecting portion is loosely penetrated. A gap is provided between the peripheral surface and the inner peripheral surface of the shaft coupling portion. In other words, the two are to be connected with a backlash.

  On the other hand, the connection receiving portion formed at the other swing end of the swing interlocking member has a push-up piece and a push-down piece facing each other up and down with a predetermined interval between them. Connection pins projecting from the rear portions of the left and right wing pieces are received between the pieces and are connected to each other. The connection receiving portion is substantially formed in a C-shaped cross section so that the push-up piece and the push-down piece face each other vertically.

  The connecting pins projecting from the back surface portion of the wing piece project rearwardly through the through holes formed in the mounting substrate at the rear end portions thereof, and slide between the upper and lower pieces of the connection receiving portion. Connected. In this connection, the connection pin is connected to the upper and lower pieces so that the state where the pin connection receiving part is not in contact with either the push-down piece or the push-up piece even when the pin connection receiving portion is in either the raised position or the lowered position. Necessary gaps are secured between them.

  The left and right wing pieces are opened and closed by pivoting left and right with respect to the mounting board as a fulcrum, and the center of gravity is moved to the left and right along with this opening and closing movement so that the closed and opened postures can be held by their own weight. It is. For this reason, the center of gravity of both blades is placed above the support shaft, and the center of gravity passes directly above the support shaft in the closed position when the center of gravity stands up and inside the support shaft in the closed position and outside in the open position. By doing so, it is urged toward each posture by its own weight.

  By the way, in the present invention, the structure is such that the expansion and contraction movement of the solenoid with respect to the solenoid is transmitted to the left and right blades through the swing of the swing interlocking member, and the plunger and the swing interlocking member are connected via the connecting shaft. The structure is such that the linear movement of the plunger is converted into a swinging movement around the fixed support shaft of the swing interlocking member. The regulation and the regulation of the rotation range of the right and left wing pieces are individually performed so that the posture maintenance at the time of opening and closing of the wing piece by the self-weight is smoothly performed.

  This relationship will be described in more detail. The rocking interlocking member regulates its rocking range directly, or regulates the range of expansion / contraction movement of the plunger, or rocks one regulating position of the rocking range. In the movement interlocking member, the other restricting position is set in the plunger, so that the swing range of the swing interlocking member is substantially restricted, whereas the pair of wing pieces that are paired on the left and right side restricts the rotation range. This is performed between the wing piece and the mounting substrate.

  The wing piece is actually pivotally attached to a support shaft that passes along the front-rear direction inside the pocket-shaped enclosure provided on the front surface of the mounting substrate, and is closed with the support shaft as a fulcrum. And an open posture inclined in the left-right direction, and the two postures are two stoppers provided on either the mounting board or the surrounding frame provided on the front surface of the mounting board. The holding range is determined by the abutting, and the rotation range between the closed position and the opening position is determined by the abutting at these two places, and is set as a restriction point.

  Further, the present invention provides a large or small difference in the restriction range between the restriction ranges determined by the two independent restriction means, and this difference causes the blade piece to reach the closed posture or the open posture and hold these postures. Therefore, when stopping, the swinging by the solenoid side, that is, the swing interlocking member is stopped immediately before that, and the pressing of the interlocking pin is released from the expansion and contraction movement of the solenoid plunger acting via the swing interlocking member. The load transmitted to the blade piece is released, and the subsequent rotation is left to the weight of the blade piece.

When the blade piece is rotated from one stop position to the other stop position, if it is urged until the center of gravity position is just above the support shaft, it will rotate by its own weight. The range of rotation of the interlocking member is preferably determined and restricted to a position where the center of gravity of the blade piece exceeds the position directly above the support shaft.
After the action of the swing interlocking member on the wing piece stops, the gap between the pin connection receiving portion and the connection pin acts effectively, and the wing piece rotates independently and is released by its own rotation restriction. Alternatively, the position of the closed posture is reached.

Now, the electric tulip of the present invention configured as described above always keeps the plunger extended by a spring that is retracted by demagnetizing the solenoid, and the left and right wing pieces on the front surface of the mounting board are erected. It will be held in a posture.
In this state, when the release instruction is received and the solenoid is excited, the plunger contracts against the spring, attracts one swing end of the swing interlocking member to swing the fixed support shaft around the fulcrum, The pin connection receiving portion provided at the swing end is flipped up. And by this movement, the interlocking pin is pushed up, and the left and right wing pieces are respectively rotated outward with the support shaft as a fulcrum. Then, by contacting the stopper, both wing pieces are held in an open posture, and a hit ball can enter.

When the closing instruction is received again in this state, the plunger is extended by the biasing of the spring with the demagnetization of the solenoid, the swing interlocking member is returned to the original position, and the blade piece is returned to the closing position.
The left and right wing pieces repeat opening and closing movements due to repeated excitation and demagnetization of the solenoid. During this opening and closing movement, one wing piece bites a hit ball with a nearby obstacle nail, for example. When the rotation is stopped, for example, when the release is instructed and the solenoid is excited and the plunger contracts, when the rotation of one wing piece is stopped, it is connected via the interlocking pin and the swing interlocking member. The contraction of the plunger is stopped in conjunction with this.
In the present invention, the connecting shaft that connects the plunger and the swing interlocking member at this time is loosely inserted into the shaft connecting portion of the swing interlocking member that passes through this, and there is a gap between them. Thus, the plunger is allowed to be retracted while the connecting shaft is twisted obliquely while leaving one shaft end connected to the swinging end where the swinging has stopped at the stop position. As a result, the other shaft end can be retracted along with this pull-in, and the other swaying interlocking member is swayed as it is to rotate the other wing piece that is free to rotate. It becomes.

  That is, when one of the blade pieces is prevented from rotating by ball engagement or the like and cannot be opened or closed, the two swing interlocking members connected via the connecting shaft supported by the plunger are connected via the connecting shaft. Since the other blade piece cannot be rotated because of the synchronously interlocking relationship, in the present invention, the connecting shaft is loosely fitted to the shaft connecting portion provided at the swing end of each swing interlocking member, When the connected state is maintained, the rotation of one of the blade pieces is prevented, and when the swinging connecting member connected to the blade piece stops swinging, the connecting shaft supported by the plunger is supported by the left and right swinging interlocking members. As the balance of the load is lost, the loosely connected connecting shaft is loosely connected, so that twisting is allowed, so that both ends of the shaft tilt forward and backward, and only one swing interlocking member swings. Free to rotate to connect to The wings in the state it become possible to rotate.

The torsion of the connecting shaft is induced by a loosely connected state between the connecting shaft and the shaft connecting portion of the swing interlocking member, and both ends of the shaft are displaced back and forth. At this time, the shaft is further inserted into the solenoid. This twist can be assisted by the rotation of the plunger.
Further, in order to smooth the twisting, the rocking interlocking member can be loosely supported by making the diameter of the insertion hole formed as the bearing portion of the plunger bearing the connecting shaft larger than the shaft diameter of the connecting shaft. The same effect as the connection to the other, and the twist can be further facilitated to facilitate the movement of the plunger, and the opening and closing movement of the other wing piece that is free to rotate can be further freed. it can.

  Therefore, according to the present invention from the above-described configuration, when one of the left and right wing pieces that open and close cannot be rotated due to ball engagement or the like, each swing interlocking member is always accompanied by the expansion and contraction of the plunger. Both wing pieces that are linked by the oscillating movement of the oscillating member can oscillate the oscillating linking member only by the torsion of the connecting shaft, and as a result, the oscillating member is allowed to open and close independently. Become. For this reason, for example, when a wing piece is opened upon receiving an opening instruction, the opening of the other wing piece is not prevented by a failure occurring in one wing piece. It will be minimal. Of course, since the rotation stop of the wing piece is not caused by the failure of the apparatus, it is eliminated at the next rotation, and the left and right wing pieces are restored to the interlocking normal state again.

  The present invention is excellent in manufacturability because it can be implemented without adding new components such as other parts by improving the connection state of the connecting shaft that connects the plunger and the left and right swing interlocking members. Accordingly, the cause of failure does not increase, so that durability is excellent and a highly reliable product can be provided.

Next, the present invention will be described in detail according to the illustrated embodiment, and the features thereof will be specifically described.

The left and right wing pieces 4a, 4b turned to the open posture are held in a state in which the inner surfaces 13a, 13b are inclined inward. As a result, in addition to the hit ball that enters through the injecting ball guide port 6, this guide port The ball that falls on the inner surfaces 13a and 13b through the outer side of 6 is received and can be used as a winning ball, so that the hitting of the hit ball is greatly eased.
The sphere that has entered through between the blades is guided to the winning opening 3 through a guide portion 19 having an arcuate guide plate formed in the center portion of the bottom plate 8, and further extends from the back surface of the mounting substrate 1. It will be led to the safe ball gathering room formed behind the game board (not shown) through the bowl 20 to be performed.

The other swinging arm is pushed down with the fixed support shaft 31 as a fulcrum, and each connecting piece 36 is pushed downward.
At this time, the swinging arms standing upright of the swing interlocking members 22a and 22b are in contact with the rear surfaces of the mounting pieces 25a and 25b of the mounting plate 24, respectively, and are used as stoppers to stop the swinging forward. Become.

When the connecting piece 36 faces downward, both the interlocking pins 37a and 37b are pushed down by the pressing pieces 36a and 36a, and are located on the lower end side of the isolated through holes 40 and 40. The left and right wing pieces 4a and 4b that rotate about the fulcrum 5 are held in an upright closed position.
At this time, a gap is provided between the interlocking pins 37a and 37b so as not to contact the lower edge of the through holes 40 and 40.
6 and 9 show a closed posture in which the blade pieces 4a and 4b stand up, and both blade pieces abut the stoppers 15 of the surrounding frame 2 on the step portions 14a and 14b at the lower ends of the inner surfaces 13a and 13a. Will keep the posture.

In this state, the blades 4a and 4b have the center of gravity position g placed inside the support shafts 5 and 5 serving as rotation fulcrums, and the stepped portions 14a and 14b are brought into contact with the stoppers 15 by their own weights, so that the posture is maintained independently. (See FIG. 9). Further, as shown in FIGS. 5 and 10, a space 41 is provided between the interlocking pins 37a and 37b and the pieces 36a and 36a of the pin coupling receiving part which is pressed down to avoid direct contact. .
The above-described gap 41 includes a restriction position where the swinging arms of the swing interlocking members 22a and 22b abut against the mounting pieces 25a and 25b of the mounting plate when the plunger 23 of the solenoid 21 is extended, and the step portions of the blade pieces 4a and 4b. 14a and 14b are formed by the difference from the positions where the stoppers 15 and 15 are in contact with the rotations of the stoppers 15 and 15 and the rotation is restricted. 37 a and 37 b are released from pressing from the connecting piece 36. Then, the direct pressing by the solenoid 21 is released.

Next, when the solenoid 21 is excited in response to the release signal in this state and the plunger 23 is pulled, the swing interlocking members 22a and 22b swing around the fixed support shaft 31 and protrude forward. , And the connecting piece 36 at the tip pushes the interlocking pins 37a and 37b positioned on the lower end side of the through holes 40 and 40 toward the upper end side.
Accordingly, with the excitation of the solenoid, the blade pieces 4a and 4b rotate with the support shafts 5 and 5 as fulcrums and the upper ends thereof outward, and the step portions 17a and 17b are brought into contact with the stoppers 18 and 18, respectively. It will stop at the point of contact.

11 to 18 show a state in which the blades 4a and 4b are rotated outward as the solenoid 21 is excited and the connection receiving portion 36 of the swing interlocking members 22a and 22b is flipped up, that is, an open posture. Shows the converted state.
When the plunger 21 is converted into an open posture by the excitation of the solenoid 21, the rear end of the plunger 23 abuts on the rear wall 38a of the insertion hole 38 and stops, and the swing interlocking members 22a and 22b swing by this stop. Stopping and pushing-up of the interlocking pins 37a and 37b by the piece 36b of the connection receiving part 36 are stopped. That is, the swing interlocking members 22a and 22b stop swinging in the opening direction using the rear wall 38a that prevents the plunger 23 from retracting when the blade pieces 4a and 4b are opened.

On the other hand, the blade pieces 4a and 4b opened by the excitation of the solenoid 21 are rotated outward by pushing up the interlocking pins 37a and 37b, and the step portions 17a and 17b are brought into contact with the stoppers 18 and 18, respectively. At this time, the center of gravity g of each blade piece 4a, 4b passes directly above the support shafts 5 and 5 and moves to the outside. When it exceeds 5 above, the winglet will automatically turn to the open position.
Of course, in this embodiment, the push-up of the interlocking pins 37a, 37b by the pin connection receiving portions 36, 36 is still continued immediately after the center of gravity position g is moved outward, whereby the left and right swing interlocking members 22a, 22b is subject to forced rotation until just before the regulation is stopped.

14 and 18 show the relationship between the pin connection receiving portion 36 and the interlocking pin 37a of the blade piece 4a in the open posture (the same applies to the interlocking pin 37b of the right blade piece 4b). A gap 42 is formed between the push-up piece 36b of the connection receiving portion 36 and the interlocking pin 37a as in the case of the closed posture.
The gap 42 is obtained by changing the position of the gap 41, but the stop position during the opening operation of the swing interlocking member 22a, that is, the retracting stop position of the plunger 23, and the stepped portion 17a of the blade piece 4a is a stopper. The wing piece 4a is released from the opening operation by the solenoid 21 at the time of stopping by this gap, and is stopped alone.

Although the electric tulip according to the present invention is not shown in the drawing, it is attached to the game board by fitting it into the through hole to be inserted from the front side, and fixing the mounting board 1 to the hole 7 with a screw when it contacts the front face of the board. become.
As described above, this electric tulip is normally in a state where the solenoid 21 is demagnetized as described above, and the plunger 23 is extended by the action of the spring 39 to thereby move the swing interlocking members 22a and 22b. The connecting piece 36 is lowered, and the blade pieces 4a and 4b are erected to maintain the closed posture. For this reason, in this embodiment, only the ball that has entered the incoming ball guiding port 6 enters the winning port 3 through the wing pieces 4a and 4b.

  In the above state, when the solenoid 21 is energized by the entry of a winning ball into the winning opening 3 or by receiving an opening instruction signal from the outside, the plunger 23 is drawn into the insertion hole 38 and the left and right The connecting pieces 36 and 36 of the swing interlocking members 22a and 22b are pushed up. For this reason, the interlocking pins 37a and 37b lowered at the time of closing are jumped up, and the wing pieces 4a and 4b on the front surface of the mounting substrate 1 are rotated outward to be converted into an open posture.

  The open posture of the wing pieces 4a and 4b is that the hit ball can easily enter as shown in the figure. Next, when a closing instruction signal is input to the solenoid in this state, the spring 39 is demagnetized and compressed. When the plunger 23 is extended by the urging force, the pin coupling receiving portions 36 and 36 descend as the swing interlocking members 22a and 22b swing, and the blades stand up by pushing down the interlocking pins 37a and 37b. Will be converted to

In this series of opening and closing operations, as described above, the electric tulip of the present invention is in the closed state of the blade pieces 4a and 4b, that is, in the closed posture, on the side of the drive mechanism portion on the solenoid 21 side including the swing interlocking members 22a and 22b. In order to convert to the above, the one swing arm of the swing interlocking members 22a and 22b is brought into contact with the mounting pieces 25a and 25b of the mounting plate 24, and this is used as a stopper to stop the swing motion. Become.
In order to convert the blade piece into the open posture, the rear end of the plunger 23 is brought into contact with the rear wall 38a of the insertion hole 38, and this is used as a stopper to stop the swing of the swing interlocking member. Thus, the swing interlocking members 22a and 22b independently limit the swing range.

  On the other hand, when the blades 4a and 4b are closed, the stepped portions 14a and 14b are brought into contact with the stoppers 15 and 15, respectively, to maintain the closed posture, while when released, the other stepped portions 17a and 17b are respectively connected to the stoppers 18 and 18. In the same manner, the blades are kept in an open posture, and the wing piece also regulates the rotation range independently.

  That is, when the blade pieces 4a and 4b are opened and closed, the regulation of the operation (swing) range of the swing interlocking members 22a and 22b by the solenoid 21 and the regulation of the operation (turning) range of the blade piece side are individually performed. In addition, by setting the operating range of the swing interlocking member to be smaller than the operating range of the blade piece, the operation of the blade pieces 4a and 4b is stopped after the swing interlocking members 22a and 22b are stopped. is there. Then, at the time of each stop, gaps 41 and 42 are formed between the push-up piece 36a and push-down piece 36b of the pin connection receiving portion 36 and the interlocking pins 37a and 37b, respectively, and the blade pieces 4a and 4b are formed by these gaps. Thus, forced pressing by the solenoid 21 can be avoided when the motor stops.

  Therefore, the electric tulip of the present invention does not receive a strong impact by the solenoid 21 when the wing piece is opened and closed. For this reason, the interlocking pins 37a and 37b for transmitting the power of the solenoid 21 to the wing piece are required to be high in the conventional electric tulip. Since the strength is not required, it is possible to use the interlocking pin that is integrally formed of a synthetic resin of the same quality as the blade piece as it is.

  The electric tulip of the present invention thus configured can open and close the left and right wing pieces 4a and 4b by driving the solenoid 21 to convert between a closed posture and an open posture. When the rotation of one wing piece is stopped by the above, the other wing piece that is linked via the connecting shaft 29 is also automatically stopped. As described above, the connecting shaft in the present invention 29 has a structure in which it is loosely connected to the plunger 23 and to one of the swinging ends of the left and right swinging interlocking members 22a and 22b, so that the connecting shaft 29 is connected to these members. It is possible to rotate the wing piece that can be rotated while absorbing the force imbalance generated in the left and right swing connecting members by being distorted, and to convert the blade piece into the open / closed posture alone.

  19 to 22 detail this relationship. FIG. 19 is an enlarged right side view of a portion where the relationship between the connecting shaft 29 and the hole 35 of the shaft connecting portion formed at one swing end of the swing interlocking member is clarified. FIG. FIG. 21 is an enlarged cross-sectional plan view of the main part showing the relationship between the connecting shaft 29, the plunger 23, and the rocking interlocking members 22a and 22b in a normal state in a state where the plunger is extended by magnetizing. FIG. FIG. 22 is an enlarged cross-sectional plan view of the main part in a normal state in which the plunger is pulled in, and FIG. 22 is an enlarged cross-sectional plan view of the main part in an abnormal state in which the plunger is pulled in by exciting the solenoid.

  When the electric tulip of the present invention is in a normal state, the plunger 23 is extended by the bias of the spring 39, and the connecting shaft 29 is pushed out so that one of the swinging ends of the left and right swinging interlocking members is placed on the back of the mounting pieces 25a and 25b. Abutting to regulate swinging. On the other hand, in this state, the blade pieces 4a and 4b are placed in the closed posture (see FIG. 20). Next, when the solenoid 21 is excited in accordance with the opening instruction in this state, the plunger 23 is pulled in while compressing the spring 39 to attract (retract) the connecting shaft 29, and the left and right swing connecting members are moved to the fixed support shaft 31. It swings to a fulcrum (FIG. 21), the other swinging end protruding forward is flipped up, and the left and right wing pieces 4a and 4b are simultaneously rotated to convert them into an open posture. .

In the normal state, the pulling of the connecting shaft 29 accompanying the pulling of the plunger 23 balances the loads of the left and right swing interlocking members 22a and 22b in this state, so that the connecting portion is loosely connected including a gap. Regardless, it will be activated at the same time and will be linked together on the left and right sides. Therefore, the left and right wing pieces 4a and 4b are rotated together in the opening direction.
Next, in this state, when any one of the wing pieces is prevented from rotating by the ball biting as described above, for example, the right wing piece 4b becomes an obstacle nail (not shown). When the hit ball is caught between them and the rotation is prevented, the rocking of the right rocking interlocking member 22b in the interlocking relationship stops, and the plunger 23 connected to this via the connecting shaft 29 As a result, the swing of the left swing interlocking member 22a is stopped, and the rotation of the left wing piece 4a is also stopped.

  However, in this restraining relationship, the present invention loosely connects the coupling shaft 29 with the holes 35 and 35 of the shaft coupling portions of the left and right swing interlocking members 22a and 22b. Since the coupling shaft 29 and the through hole 23a of the plunger 23 are loosely fitted to provide the gaps a and b, respectively, when the swing of the right swinging interlocking member 22b stops, the gap a Then, the connecting shaft 29 drawn by the plunger 23 by the gap b tilts both ends back and forth, and twists the posture while retracting the left end while leaving the right end (refer to FIG. 22), thereby interlocking to the left. The left wing piece 4a, which is allowed to swing while allowing the member 22a to swing, is rotated in the opening direction.

  This operation is the same when the left wing piece 4a becomes unrotatable. In this case, only the right wing piece 4b is turned and converted into an open posture. Of course, the impossibility of rotation of the blade pieces 4a and 4b occurs even when the blade pieces are closed. In this case, the connection is made to connect to the swing interlocking member on the side where the swing is stopped with respect to the plunger 23 returned by the spring 39. The other end is swung while leaving the end portion of the shaft 29, and one blade piece is converted into a closed posture.

The wing pieces that cannot be rotated by the above-mentioned ball biting, etc., will recover the normal operation by removing the bite by receiving an impact by the following opening / closing operation under normal use. become. Of course, in the case of firmness, the worker removes it, but during this time, at least both blade pieces remain open or closed.
As described above, when the left and right wing pieces 4a and 4b are rotated, the posture position is converted by swinging the center of gravity of the support shafts 5 and 5 to the left and right, and the swing interlocking member is further moved. When the gaps 41 and 42 described above are prepared between the pin connection receiving portion 36 and the connection pin 37 of the wing piece, even if the inclination of the connection shaft 29 is small at the time of the abnormality, the movement is supplemented and ensured. This is effective because it achieves a change in the opening and closing posture.

  Further, in order to assist the tilting state of the connecting shaft 29 at the time of the abnormality, if the diameter of the insertion hole 38 of the solenoid 21 is slightly larger than the shaft diameter of the plunger 23 and a gap is provided between them, Since the inclination of the connecting shaft during expansion and contraction is further helped by this gap, it is effective because the swing of the other swing interlocking member can be increased with respect to the one swing interlocking member to be stopped. .
